Thomas brought the safe water filter to the Adhocracy London exhibition

After years spent in the field (my last field assignment was Head of Delegation of the British Red Cross in Haiti following the quake) and a job in London with DfID, I discovered the huge potential of membrane technology and its game changing impact. Leaving a prestigious organisation such as DfID to join what, at the time, was an almost unknown company was a challenge that I do not regret to have accepted.

Water that is contaminated by biological pollution is one of the biggest problems being faced by the developing world as well as individuals and families who are either victims of catastrophic natural disasters or who have been caught up in humanitarian crises arising from armed conflict.

The Safe Water Trust is a UK charitable company limited by guarantee that designs and manufactures GrifAid® water filters that use ultrafiltration membrane technology. The filters do not remove dissolved chemicals, salts or nitrates but they do remove all particulate and biological material including all viruses and bacteria larger than 0.01 microns. This means that surface or groundwater that is polluted by biological pathogens can be made safe to drink. The filters do not require spare parts, replacement cartridges, chemicals, electricity or maintenance and many GrifAid® units have been in daily use for more than 5 years in more than 40 countries around the world. Depending on the model, the filters produce between 90 and 300 litres of clean, safe water per hour.
